Within the general classes of communication media, there are those specific ones that will match well defined communication need. The architect must be assured that the alternate costs and flow times are favorable in terms of the total communication value of the medium. Architect's disciplinary communication media are established on graphical symbols such as plans, sections, elevations, perspectives etc. The communication media of computers are entirely different from those of the architects. This communication gap between architects and the computer have a detrimental effect on the use of computers by architects. If a graphical information medium is designed between the architects and the computer the architect will, then best exploit the possibilities of the computer. Perspective drawings are the most favorable graphical instruments for the presentation of the three-dimensional objects. 1 They are helpful to simulate the perceiving of space. The architect can evaluate the spacious quality of his/her design proposal by checking the drawings. He can also use the drawings to present his design to the client or the partners or any other interested group. Besides these usages, the computer can give outputs for some programs as perspective drawings if programmed so. There is a number of computer programs on perspective drawings already prepared. 2 Some of the programs can also be called by other technical programs to transfer output data graphically. In the following paragraphs, the process of defining the three-dimensional objects int o computer, the model of the perspective projection and an outstanding problem of perspective projection which is called hidden-line problem are discussed in detail, and some sample outputs are given. In the last section the program generating the model is described, and the physical characteristics of the program are given
